The sampling technique that divides the population into subgroups before selecting participants is **Stratified sampling**.
In stratified sampling, the population is divided into distinct subgroups (or strata) based on specific characteristics (such as age, gender, income level, etc.), and then participants are randomly selected from each subgroup. This method ensures that the sample represents the diversity of the population.
